Onshore Wind Cost Reduction Taskforce Report

Onshore wind is the UK’s lowest-cost large-scale renewable
generation technology. Costs have more than halved in real
terms since the first commercial turbines were erected in
the early 1990s, and are expected to continue to fall. The
industry is committed to taking active steps to cut the cost of
wind energy to ensure onshore wind is the lowest-cost new
generation technology in the UK by 2020.
